van't Hoff factors of equimolal solutions of sodium chloride, barium chloride and glucose in water are
- A \(2,3,0\) respectively
- B \(2,3,6\) respectively
- C \(2,3,4\) respectively
- D \(2,3,1\) respectively
Answer & Solution
Correct Answer
(D) \(2,3,1\) respectively
Step-by-step Solution
Detailed explanation
\(\mathrm{NaCl}(a q) \longrightarrow \mathrm{Na}^{+}(a q)+\mathrm{Cl}^{-}(a q)\) van't Hoff factor, \(i=2\) \(\mathrm{BaCl}_{2}(a q) \longrightarrow \mathrm{Ba}^{2+}(a q)+2 \mathrm{Cl}^{-}(a q), i=3\) Glucose does not undergo dissociation or association hence, \(i=1\)
